Understanding Tire Markings
Laws require tire manufacturers to place standardized information on the sidewall of all tires. This information
identifies and describes the fundamental characteristics of the tire. It also provides the tire identification number
(TIN) for certification of safety standards, and in case of a recall.
1Tire category. P indicates that the tire is for passenger vehicles.2Tire width. This 3-digit number is the width (in millimeters) of the tire from sidewall edge to sidewall edge.3Aspect ratio. This 2-digit number is the sidewall height as a percentage of the tread width. So, if the tread width is 205 mm, and the aspect ratio is 50, the sidewall height is 102 mm.4Tire construction. R indicates that the tire is of Radial ply construction.5Wheel diameter. This 2-digit number is the diameter of the wheel rim in inches.6Load index. This 2 or 3-digit number is the weight each tire can support. This number is not always shown.7Speed rating. When stated, indicates the maximum speed (in mph) at which the tire can be used for extended
periods. Q=99 mph (160 km/h), R=106 mph (170 km/h), S=112 mph (180 km/h), T=118 mph (190 km/h), U=124 mph (200 km/h), H=130 mph (210 km/h), V=149 mph (240 km/h), W=168 mph (270 km/h), Y=186 mph
(300 km/h), (Y)=vehicle
Tire and Loading Glossaries
General Wheel and Tire Terms
Accessory WeightThe combined weight (in excess of those items replaced) of items available as factory
installed equipment.BeadThe inner edge of a tire that is shaped to fit to the rim and form an air tight seal. The
bead is constructed of steel wires which are wrapped, or reinforced, by the ply cords.Cold Tire PressureThe air pressure in a tire that has been standing in excess of three hours, or driven for less than one mile.Curb WeightThe weight of a standard vehicle, including any optional equipment fitted, and with the
correct
fluid levels.
Gross Vehicle WeightThe maximum permissible weight of a vehicle with driver, passengers, load, luggage, and
equipment.kPa (kilo pascal)A metric unit used to measure pressure. One kilo pascal equals approximately 0.145 psi.Maximum Inflation
Pressure
The maximum pressure to which the tire should be inflated. This pressure is given on the
tire side wall in psi (lbf/in2).
CAUTION: This pressure marked on the tire is the maximum allowed by the tire
manufacturer. It is not the pressure Tesla recommends using for Model Y.
Maximum Loaded

of the tables for calculating load limits (see
Vehicle Loading on page 182).
Occupant distributionDistribution of occupants in a vehicle.Passenger car tireA tire intended for use on passenger cars, multipurpose passenger vehicles, and trucks, that have a gross vehicle weight rating (GVWR) of 10,000 lbs (4536 kg) or less.Rim diameterNominal diameter of the bead seat.Rim size designationRim diameter and width.Rim type designationThe manufacturing industry
Vehicle normal load on the
tireLoad on an individual tire that is determined by distributing to each axle its share of
the curb weight, accessory weight, and normal occupant weight and dividing by two.
Pneumatic Radial Tire Definitions
Bead separationA breakdown of the bond between components in the bead.Bias ply tireA pneumatic tire in which the ply cords that extend to the beads are laid at alternate angles
substantially less than 90 degrees to the center line of the tread.CarcassThe tire structure, except tread and sidewall rubber which, that when inflated, bears the load.ChunkingThe breaking away of pieces of the tread or sidewall.CordThe strands forming the plies in the tire.Cord separationThe parting of cords from adjacent rubber compounds.CrackingAny parting within the tread, sidewall, or inner liner of the tire extending to cord material.Extra load tireA tire designed to operate at higher loads and higher inflation pressure than the
corresponding standard tire.GrooveThe space between two adjacent tread ribs.Inner linerThe layer(s) forming the inside surface of a tubeless tire that contains the inflating medium
within the tire.Inner liner
separationThe parting of the inner liner from cord material in the carcass.Load ratingThe maximum load that a tire is rated to carry for a given inflation pressure.Maximum load
ratingThe load rating for a tire at the maximum permissible inflation pressure for that tire.Measuring rimThe rim on which a tire is fitted for physical dimension requirements.Open spliceAny parting at any junction of tread, sidewall, or inner liner that extends to the cord material.Outer diameterThe overall diameter of an inflated new tire.Overall widthThe linear distance between the exteriors of the sidewalls of an inflated tire, including
elevations due to labeling, decorations, or protective bands or ribs.PlyA layer of rubber-coated parallel cords.Ply separationA parting of rubber compound between adjacent plies.Pneumatic tireA mechanical device made of rubber, chemicals, fabric and steel or other materials, that,
when mounted on an automotive wheel, provides the traction and contains the gas or
fluid
that sustains the load.
Radial ply tireA pneumatic tire in which the ply cords that extend to the beads are laid at substantially 90
degrees to the center line of the tread.Reinforced tireA tire designed to operate at higher loads and at higher inflation pressures than the
corresponding standard tire.Section widthThe linear distance between the exteriors of the sidewalls of an inflated tire, excluding
elevations due to labeling, decoration, or protective bands.SidewallThe portion of a tire between the tread and bead.Sidewall separationThe parting of the rubber compound from the cord material in the sidewall.
Wheels and Tires
194MODEL Y Owner
DO NOT TRANSPORT WITH
WHEELS ON THE GROUND
The rear motor in Model Y generates power when the
wheels spin. Always transport
Model Y with all four tires
off the ground. Ensure that the tires are unable to spin at
any time during transport.
WARNING: NEVER TRANSPORT YOUR VEHICLE
WITH THE TIRES IN A POSITION WHERE THEY
CAN SPIN. DOING SO CAN LEAD TO SIGNIFICANT
DAMAGE AND OVERHEATING. IN RARE CASES
EXTREME OVERHEATING MAY CAUSE THE
SURROUNDING COMPONENTS TO IGNITE.
Do not transport Model Y using any method that is not
specified by Tesla. Adhere to the instructions provided in
the following sections and observe all warnings and
cautions provided. Damage caused by improper
transporting of your vehicle is not covered by the
warranty.
NOTE: Tesla is not liable or responsible for reimbursing
services not dispatched through Tesla Roadside Assistance.
Approved Methods for Transporting
NOTE: The tires are allowed to rotate slowly (under 3
mph or 5 km/h) and for a very short distance (less than
30 feet or 10 meters) only when Transport Mode is
enabled (see
Activate Transport Mode on page )
while the vehicle is being winched onto a
flatbed truck
or pulled out of a parking space for repositioning.
Exceeding these boundaries can lead to
significant
damage and overheating that is not covered by the
warranty.
A flatbed truck or comparable transport vehicle is the
recommended method of transporting
Model Y. The
vehicle can face either direction when using a
flatbed.
If Model Y must be transported without a flatbed truck,
then wheel lifts and dollies must be used to ensure that
all four wheels are
off of the ground. This method may
only be used for a maximum of
35 miles (55 km), and
must not exceed the manufacturer speed rating of the
dollies. With this method, Tesla recommends the vehicle
facing forward so that the front wheels are lifted and the rear wheels are on dollies.
CAUTION: Enable Transport Mode (see Activate
Transport Mode on page ) before winching
Model Y onto a flatbed truck (see Pull Onto
Flatbed Truck From Front on page and Pull
Onto Flatbed Truck From Rear on page ). If
Transport Mode is not available or the touchscreen
is not accessible, self-loading dollies or tire skates
must be used to load the vehicle into the approved
transportation position. Tesla is not responsible for
any damage caused by or during the transport of
Model Y, including personal property damage or
damage caused by using self-loading dollies or tire
skates.
WARNING: Model Y is equipped with high voltage
components that may be compromised as a result
of a collision (see High Voltage Components on
page 156). Before transporting Model Y, it is
important to assume these components are
energized. Always follow high voltage safety
precautions (wearing personal protection
equipment, etc.) until emergency response
professionals have evaluated the vehicle and can
accurately confirm that all high voltage systems
are no longer energized. Failure to do so may
result in serious injury.
Activate Transport Mode
Transport Mode keeps the parking brake disengaged
while winching
Model Y onto a flatbed truck. When
active, Transport Mode displays a message indicating that the vehicle will remain free-rolling. The following are
required to enable Transport Mode:
2.
Release the rear tow eye cover by pressing firmly on
its top right perimeter until it pivots inward, then
gently pulling the raised section toward you.
NOTE: Vehicles equipped with a hitch receiver cannot
be pulled from the rear tow eye. Use the tow bar or
hitch receiver only to pull the vehicle to a safe
location, such as onto a
flatbed truck. Do not
transport the vehicle with wheels on the ground.
3.
Fully insert the tow eye into the opening, then turn it
counter-clockwise until securely fastened.
4.
Attach the winch cable to the tow eye.
CAUTION: Before pulling, make sure the tow
eye is securely tightened.
5.
Activate Transport Mode.
6.
Pull Model Y slowly onto the flatbed truck.
